CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation of PCT/KR2022/015808, filed on Oct. 18, 2022, at the Korean Intellectual Property Receiving Office and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2021-0174486, filed Dec. 8, 2021, in the Korean Intellectual Property Office, and to Korean Patent Application No. 10-2022-0016203, filed Feb. 8, 2022, in the Korean Intellectual Property Office, the disclosures of each which are incorporated by reference herein in their entireties.

BACKGROUND 1. Field

The disclosure relates to a wearable electronic device implementing a distributed system for processing contents and a vision.

2. Description of Related Art

Wearable electronic devices, such as augmented reality (AR) glasses, which provide augmented realities (ARs), have been developed. The wearable electronic device may include a display provided in correspondence to two lenses for reproduction of contents and a plurality of cameras for identifying AR motions.

SUMMARY

A system associated with reproduction of contents of a wearable electronic device and a system for identifying AR motions may be implemented by a single system. In this case, power consumption may be concentrated at a location at which the single system is mounted, and a hot spot, at which emitted heat is concentrated at a peripheral portion of the single system, may be generated.

To remove the hot spot, an additional structure may be provided. However, a deviation of weight may be generated due to an additional heat dissipating structure. An additional structure for balancing the weight may be installed on an opposite side to remove the deviation of the weight. However, the additional structure for balancing the weight may increase the total weight of the wearable electronic device. A hot spot, weight imbalance, and a heavy weight of the wearable electronic device may degrade a comfort of wearing of a user.

Furthermore, because signal lines used in the wearable electronic device implementing the single system also are concentrated, it may be difficult to design various form factors of the wearable electronic device.

The disclosure provides an electronic device implementing a distributed system, by which a balance of a weight thereof may be maintained and an unnecessary increase of the weight may be prevented or reduced by removing a hot spot.

The wearable electronic device according to an embodiment may include a frame, a first arm and a second arm extending from the frame, respectively, a screen display disposed in the frame, and including a display, at least one camera disposed in the frame, a first processor located in the first arm, and operatively connected to the display, and a second processor located in the second arm, and operatively connected to the at least one camera, the first processor may be configured to display contents on the screen display using the display, and the second processor may be configured to perform an operation associated with the at least one camera.

The wearable electronic device according to an embodiment may include a frame, a first arm extending from a periphery portion of the frame in a first direction, a second arm extending from a periphery portion of the frame in an opposite direction to the first direction, a screen display disposed in the frame, and including a display, a plurality of sensors disposed in the frame, including a head tracking sensor and a gaze-tracking sensor, a first system that processes contents displayed on the screen display part, and a second system that processes a value detected by the sensors, and the first system may be disposed in the first arm and the second system may be disposed in the second arm.

According to the embodiments disclosed in the disclosure, emitted heat of an electronic device may be uniformly distributed and a hot spot may be removed through a distributed system for processing contents and a vision.

According to the embodiments disclosed in the disclosure, design restrictions due to a volume of the electronic device and a mounting space of signal lines may be reduced through the distributed system for processing contents and a vision.

According to the embodiments disclosed in the disclosure, a balance of the weight may be maintained without any unnecessary increase of the weight and a comfort of wearing of the user may be enhanced.

In addition, the disclosure may provide various effects that are directly or indirectly recognized.

DETAILED DESCRIPTION

Hereinafter, various embodiments of the disclosure will be described with reference to the accompanying drawings. It will be recognized that modification, equivalent, and/or alternative on the various embodiments described herein can be variously made without departing from the scope and spirit of the disclosure.

FIG. 1A is a schematic view of an example electronic device 101 according to various embodiments. FIG. 1B is a schematic view of the example electronic device 101 according to various embodiments. In FIG. 1A, illustration of a third printed circuit board (PCB) 487 of FIG. 1B is omitted, but this is for convenience of description, and the disclosure is not limited to the embodiment illustrated in FIG. 1A or FIG. 1B. Similarly, in FIG. 1B, illustration of some configurations of the electronic device 101, except for the third PCB 487, is omitted.

In the examples of FIGS. 1A and 1B, the electronic device 101 may be referenced as a head mounted display (HMD) device, a wearable device, smart glasses, an eyewear, an augmented reality (AR) device, or a virtual reality (VR) device. The shape of the electronic device 101 illustrated in FIGS. 1A and 1B is by way of example, and the embodiments of the disclosure are not limited thereto.

Referring to FIG. 1A, the electronic device 101 (e.g., an electronic device 301 of FIG. 3 ) according to an embodiment may include a frame (or a frame structure) 197, a first arm 193-1, and a second arm 193-2. The frame 197 may include a first member 197-1, in which a first transparent member 196-1 is disposed, a second member 197-2, in which a second transparent member 196-2 is disposed, and a third member 197-3 that connects the first member 197-1 and the second member 197-2. At least some of the first member 197-1, the second member 197-2, and/or the third member 197-3 may be integrally formed, but the disclosure is not limited thereto. The first arm 193-1 and the second arm 193-2 may extend from the frame 197, respectively. For example, the first arm 193-1 may extend from a first side peripheral portion (e.g., a peripheral portion of the first member 197-1 in the +Y direction) of the first member 197-1, and the second arm 193-2 may extend from a second side peripheral portion (e.g., a peripheral portion of the second member 197-2 in the −Y direction) of the second member 197-2, which is opposite to the first side. The first arm 193-1 and the second arm 193-2 may be physically connected to the frame 197. For example, the first arm 193-1 may be connected to the first member 197-1, and the second arm 193-2 may be connected to the second member 197-2. When a user wears the electronic device 101, the frame 197 may be located on a front surface (e.g., the +X direction) of the head of the user, the first arm 193-1 may be located on a first side (e.g., the +Y direction) of the head of the user, and the second arm 193-2 may be located on a second side (e.g., the −Y direction) of the head of the user that is opposite to the first side. Furthermore, when the user wears the electronic device 101, the first member 197-1 of the frame 197 may correspond to the right eye of the user, and the second member 197-2 may correspond to the left eye of the user. Furthermore, the first arm 193-1 and the second arm 193-2 may support the frame 197 when the electronic device 101 is mounted.

In an embodiment, the first arm 193-1 may include a first sub-arm 195-1, a second sub-arm (or a first temple) 198-1, and a first hinge part 199-1. The first sub-arm 195-1 may be connected to the first member 197-1 of the frame 197. The second sub-arm 198-1 may be connected to the first sub-arm 195-1 to be rotatable through the first hinge part 199-1. For example, the second sub-arm 198-1 may be folded inwards with respect to the first sub-arm 195-1 or be spread outwards, in correspondence to an operation of the first hinge part 199-1. In an embodiment, the second arm 193-2 may include a third sub-arm 195-2, a fourth sub-arm (or a second temple) 198-2, and a second hinge part 199-2. The third sub-arm 195-2 may be connected to the second member 197-2 of the frame 197. The fourth sub-arm 198-2 may be connected to the third sub-arm 195-2 to be rotatable through the second hinge part 199-2. For example, the fourth sub-arm 198-2 may be folded inwards with respect to the third sub-arm 195-2 or be spread outwards, in correspondence to an operation of the second hinge part 199-2. In the disclosure, the frame 197, the first arm 193-1, and the second arm 193-2 may be referenced as a “housing” of the electronic device 101.

In an embodiment, at least a partial area of a surface of the housing of the electronic device 101 may include a sensing area for detecting a touch input by the user. For example, a surface 1981 of the first arm 193-1, which faces the first side (e.g., the +Y direction) may be at least partially used as the sensing area.

The electronic device 101 according to an embodiment may include a display 161 (e.g., a display module 360 of FIG. 3 ). For example, the electronic device 101 may include a first display 161-1 and/or a second display 161-2. The first display 161-1 may be disposed in the first member 197-1 of the frame 197 and/or the first sub-arm 195-1 of the first arm 193-1. The second display 161-2 may be disposed in the second member 197-2 of the frame 197 and/or the third sub-arm 195-2 of the second arm 193-2.

In an embodiment, the first display 161-1 and/or the second display 161-2 may include at least one of a liquid crystal display (LCD), a digital mirror device (DMD), a liquid crystal on silicon (LCoS) device, an organic light emitting diode (OLED), or a micro light emitting diode (micro LED). The display 161 of the electronic device 101 may include at least one light source for irradiating light. For example, when the first display 161-1 and/or the second display 161-2 includes one of a liquid crystal display device, a digital mirror device, or a silicon liquid crystal display device, the electronic device 101 may include at least one light source that irradiates light to a screen output area 160-1 and/or 160-2 of the display 161. In an embodiment, when the display 161 of the electronic device 101 generates light by itself, the display 161 may not include a separate light source other than a light source included in the display 161. For example, when the first display 161-1 and/or the second display 161-2 includes at least one of an organic light emitting diode or a micro LED, the electronic device 101 may provide an image to the user even though a separate light source is not included. Because a separate light source is not necessary when the display 161 is implemented by an organic light emitting diode or a micro LED, a weight of the electronic device 101 may be reduced.

The electronic device according to an embodiment may include the first transparent member 196-1 and the second transparent member 196-2. The first transparent member 196-1 may be at least partially accommodated in a window defined by the first member 197-1 of the frame 197. The second transparent member 196-2 may be at least partially accommodated in a window defined by the second member 197-2 of the frame 197. When the user wears the electronic device 101, the user may see through the first transparent member 196-1 and/or the second transparent member 196-2. The first transparent member 196-1 and/or the second transparent member 196-2 may be formed of at least one of a glass plate, a plastic plate, or a polymer, and may be substantially transparent or translucent. When the electronic device 101 is mounted, the first transparent member 196-1 may be disposed to face the right eye of the user, and the second transparent member 196-2 may be disposed to face the left eye of the user.

In an embodiment, at least a portion of the first transparent member 196-1 and/or the second transparent member 196-2 may be a waveguide. The waveguide may deliver an image generated by the display 161 to the eyes of the user. The waveguide may be formed of glass, plastic, or a polymer. For example, the waveguide may include a nano pattern (e.g., a polygonal or curved grating structure) formed in an interior or on one surface thereof. The light that is input to one end of the waveguide may propagate in an interior of the waveguide by the nano pattern and may be provided to the eyes of the user. As an example, the waveguide including a free-form type prism may be configured to provide the input light to the user through a reflective mirror.

According to an embodiment, the waveguide may include at least one of at least one diffractive element (e.g., a diffractive optical element or a holographic optical element) or a reflective element (e.g., a reflective mirror). The waveguide may guide the light emitted from a light source to the eyes of the user using the at least one diffractive element or reflective element. For example, the diffractive element may include an input optical member (e.g., 162-1 and/or 162-2) and/or an output optical member (not illustrated). The first input optical member 162-1 and/or the second input optical member 162-2 may be referenced as, for example, an input grating area, and the output optical member (not illustrated) may be referenced, for example, as an output grating area. The input grating area may diffract or reflect the light to deliver the light output from a light source (e.g., a micro LED) to the transparent member (e.g., the first transparent member 196-1 and/or the second transparent member 196-2) of the screen display part. The output grating area may diffract or reflect the light delivered to the transparent member (e.g., the first transparent member 196-1 and/or the second transparent member 196-2) of the waveguide in a direction of the eyes of the user. For example, the reflective element may include a total-reflection optical element or a total-reflection waveguide for total internal reflection (TIR). The total internal reflection may be referenced as one scheme of guiding light, and may refer, for example, to an incident angle being made such that the light (e.g., the image) input through the input grating area is reflected on one surface of the waveguide (e.g., a specific surface) by 100% and the light is delivered to the output grating area by 100%. In an embodiment, a light path of the light emitted from the display 161 may be guided to the waveguide by the input optical member. The light that travels in the interior of the waveguide may be guided to the direction of the eyes of the user through the output optical member. The screen output area 160-1 and/or 160-2 may be determined based on the light emitted in the direction of the eyes.

FIG. 1A illustrates that the electronic device 101 provides an image to the user using the waveguide, but the embodiments of the disclosure are not limited thereto. For example, the display 161 of the electronic device 101 may be a transparent or translucent display. In this case, each of the first display 161-1 and the second display 161-2 may be disposed at a location (e.g., the first screen output area 160-1 and/or the second screen output area 160-2) that faces the eyes of the user. Furthermore, each of the first display 161-1 and the second display 161-2 may be disposed to at least partially overlap the first transparent member 196-1 and/or the second transparent member 196-2. For example, the first display 161-1 may be disposed on the first transparent member 196-1, or the first display 161-1 may be interposed between a plurality of layers of the first transparent member 196-1 when the first transparent member 196-1 includes a plurality of layers. Additionally or selectively, the second display 161-2 may be disposed on the second transparent member 196-2, or the second display 161-2 may be interposed between a plurality of layers of the second transparent member 196-2 when the second transparent member 196-2 includes a plurality of layers. In this disclosure, at least one of the input optical member 162, the transparent member 196, and the display 161, which outputs light to provide a screen that may be viewed by the user, and redirects the output light, may be referred to as a “screen display part” or “screen display”.

According to an embodiment, the electronic device 101 may include at least one camera (e.g., a camera module 380 of FIG. 3 ). For example, the electronic device 101 may include a first camera 180-1, a second camera 180-2, and/or a third camera 180-3, which are disposed in the frame 197. The first camera 180-1 may be disposed in the first member 197-1 of the frame 197 to be adjacent to the first display 161-1. The second camera 180-2 may be disposed in the second member 197-2 of the frame 197 to be adjacent to the second display 161-2. The third camera 180-3 may be disposed in the third member 197-3 of the frame 197. Each of the first camera 180-1, the second camera 180-2, and the third camera 180-3 may include one or a plurality of cameras.

The first camera 180-1 and the second camera 180-2, for example, may be used to recognize an external image. The first camera 180-1 and the second camera 180-2 may be configured to acquire an image corresponding to a direction (e.g., the +X direction) corresponding to a gaze of the user who wears the electronic device 101. The electronic device 101 may perform head tracking (e.g., three or six degrees of freedom (DoF) tracking), hand image detection, hand image tracking, and/or space recognition) using the first camera 180-1 and the second camera 180-2. As an example, the first camera 180-1 and the second camera 180-2 may be global shutter (GS) cameras that have the same standard and performance (e.g., an angle of view, a shutter speed, a resolution, and/or the number of color bits). The electronic device 101 may support simultaneous localization and mapping (SLAM) technology by performing space recognition (e.g., space recognition of six degrees of freedom) and/or acquisition of depth information using stereo cameras disposed on the left and right sides. Furthermore, the electronic device 101 may recognize a gesture of the user using the stereo cameras disposed on the left and right sides. The electronic device 101 may detect fast hand motion and fine motion using the GS camera having small distortion as compared with a rolling shutter (RS) camera.

The third camera 180-3, for example, may be used for recognition of an external image. The third camera 180-3 may be configured to acquire an image corresponding to a direction (e.g., the +X direction) corresponding to a gaze of the user. In an embodiment, the third camera 180-3 may be a camera having a relatively high resolution as compared with the resolutions of the first camera 180-1 and the second camera 180-2. The third camera 180-3 may be referred to, for example, as a high resolution (HR) camera or a photo video (PV) camera. The third camera 180-3 may support functions for acquiring a high-quality image, such as auto focus (AF) and/or optical image stabilization (OIS). The third camera 180-3 may be a GS camera or an RS camera.

According to an embodiment, the electronic device 101 may include at least one gaze-tracking sensor (e.g., a sensor module 376 of FIG. 3 ). For example, the electronic device 101 may include a first gaze-tracking sensor 176-1 and/or a second gaze-tracking sensor 176-2. Each of the first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2, for example, may include at least one camera (e.g., a third camera 480-3 and a fourth camera 480-4 of FIG. 4 ) that is configured to acquire an image in a direction corresponding to the eyes of the user. The first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2 may be configured to acquire an image of the right pupil of the user and an image of the left pupil of the user, respectively. The electronic device 101 may be configured to detect the pupils of the user, based on the image of the pupils acquired using the first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2. For example, the electronic device 101 may detect a location (or a gaze) and a location change (or a gaze change) of the pupil of the user, based on an image of the pupil. The electronic device 101 may acquire a gaze (or data on the gaze) of the user, based on the image of the pupil of the user, and may display contents (e.g., an image) on the screen display part, based on the acquired gaze. For example, the electronic device 101 may display the image in the first transparent area 196-1 and/or the second transparent area 196-2 such that the image is located in the direction of the gaze of the user, using the display 161. As an example, the first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2 may be global shutter (GS) cameras that have the same standard and performance (e.g., an angle of view, a shutter speed, a resolution, and/or the number of color bits), but the disclosure is not limited in this respect.

According to various embodiments, the electronic device 101 may include at least one lighting unit. The lighting unit, for example, may include at least one LED. For example, the electronic device 101 may include a first lighting unit 181-1 and/or a second lighting unit 181-2. The first lighting unit 181-1 and the second lighting unit 181-2 may be disposed in the frame 197. For example, the first lighting unit 181-1 may be disposed in the first member 197-1 of the frame 197, and the second lighting unit 181-2 may be disposed in the second member 197-2 of the frame 197. The first lighting unit 181-1 and the second lighting unit 181-2 may be adjacent to the first camera 180-1 and the second camera 180-2, respectively. The first lighting unit 181-1 and the second lighting unit 181-2 may provide auxiliary lighting for the first camera 180-1 and the second camera 180-2, respectively. Although not illustrated, the electronic device 101 may include a third lighting unit disposed adjacent to the third camera 180-3. The third lighting unit may provide auxiliary lighting for the third camera 180-3.

In an example, the electronic device may include lighting units (not illustrated) disposed at peripheral portions of the first transparent member 196-1 and the second transparent member 196-2, respectively, in the frame 197. For example, each of the lighting units may be disposed in the third member 197-3 of the frame 197 to be adjacent to the first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2. Alternatively, each of the lighting units may be included in the first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2 to be implemented integrally. The lighting units are disposed to face the pupils of the user to provide lighting (e.g., light of a wavelength of an infrared ray) for allowing the first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2 to acquire a pupil image. The lighting units may include an LED that is configured to emit light of a wavelength of an infrared ray. Each of the first gaze-tracking sensor 176-1 and the second gaze-tracking sensor 176-2 may include an image sensor for acquiring an image of a wavelength of an infrared ray.

According to an embodiment, the electronic device 101 may include at least one battery (e.g., a battery 389 of FIG. 3 ). For example, the electronic device 101 may include a first battery 189-1 located at one end of the second sub-arm 198-1 and a second battery 189-2 located at one end of the fourth sub-arm 198-2. The first battery 189-1 and the second battery 189-2 may be configured to supply electric power to the elements of the electronic device 101.

According to an embodiment, the electronic device 101 may include at least one speaker (e.g., a sound output module 355 of FIG. 3 ). For example, the electronic device 101 may include a first speaker 170-1 and a second speaker 170-2. The first speaker 170-1 and the second speaker 170-2 may be disposed in the second sub-arm 198-1 and the fourth sub-arm 198-2, respectively. The electronic device 101 may be configured to provide stereo sounds using the speakers located on the left and right sides.

According to an embodiment, the electronic device 101 may include at least one microphone (e.g., an audio module 370 of FIG. 3 ). For example, the electronic device 101 may include a first microphone 171-1, a second microphone 171-2, and/or a third microphone 171-3. The first microphone 171-1, the second microphone 171-2, and the third microphone 171-3 may be disposed in the first member 197-1, the second member 197-2, and the third member 197-3 of the frame 197, respectively. For example, the first microphone 171-1 and the second microphone 171-2 may be disposed at lower ends of the first member 197-1 and the second member 197-2, respectively, but the disclosure is not limited in this respect.

Referring to FIGS. 1A and 1B, the electronic device 101 according to an embodiment may include a first PCB 187-1, a second PCB 187-2, and the third PCB 487. The first PCB 187-1 and the second PCB 187-2 may be disposed in a second sub-arm 198-1 of the first arm 193-1 and a fourth sub-arm 198-2 of the second arm 193-2 respectively. The first PCB 187-1 and the second PCB 187-2 may be electrically connected to other elements of the electronic device 101 through signal lines and/or a flexible PCB (FPCB). Each of the first PCB 187-1 and/or the second PCB 187-2 may be implemented by a substrate assembly including a plurality of PCBs and interposers disposed between the plurality of PCBs, but the disclosure is not limited in this respect.

In an embodiment, the third PCB 487 may be disposed in the first arm 193-1, the frame 197, and the second arm 193-2. The third PCB 487 may extend from the first arm 193-1 to the second arm 193-2 over the frame 197. For example, the third PCB 487 may extend along an outer surface of the housing, in the first arm 193-1, the frame 197, and the second arm 193-2. The third PCB 487 may at least partially include a flexible portion to be bent along a shape of the housing. For example, a fourth part 4874 of the third PCB 487 that extends from the first sub-arm 195-1 along a periphery of the first member 197-1 of the frame 197 may be formed flexibly. The fourth part 4874 may include a portion that is bent at a border between the first sub-arm 195-1 and the first member 197-1 and a portion that is bent along a shape of the first member 197-1. Furthermore, a fifth part 4875 of the third PCB 487 that extends from the third sub-arm 195-2 along a periphery of the second member 197-2 of the frame 197 may be formed flexibly. The fifth part 4875 may include a portion that is bent at a border between the third sub-arm 195-2 and the second member 197-2 and a portion that is bent along a shape of the second member 197-2.

In an embodiment, a first part 4871, a second part 4872, and a third part 4873 of the third PCB 487 may be formed rigidly. The first part 4871 and the second part 4872 may be located at opposite ends of the fourth part 4874, and may be connected to each other by the fourth part 4874. The first part 4871 may be connected to the first PCB 187-1 through a connection member 1 that passes through the first hinge part 199-1.

A scheme corresponding to the description made with reference to the second PMIC 488-2 may be applied to the fourth PMIC 488-4. For example, the fourth PMIC 488-4 may prevent or reduce overcharge of the second battery 489-2, and manage an output voltage and monitor a residual amount. Alternatively, the fourth PMIC 488-4 may be integrated with the second PMIC 488-2, and in this case, the second PMIC 488-2 may perform substantially the same function as that of the fourth PMIC 488-4.

In an embodiment, the first processor 420-1 of the content system 410 may execute instructions stored in the first memory 432-1 (e.g., a memory 330 of FIG. 3 ). The electronic device 401 may control the content system 410 by executing the instructions stored in the first memory 432-1 using the first processor 420-1.

The second processor 420-2 (e.g., the processor 320 of FIG. 3 ) of the vision system 412 may execute instructions stored in a second memory 432-2 (e.g., the memory 330 of FIG. 3 ). The electronic device 401 may control the vision system 412 by executing the instructions stored in the second memory 432-2 using the second processor 420-2.

In an embodiment, the content system 410 and the vision system 412 may be operated independently. Selectively, a transmission line for synchronizing the content system 410 and the vision system 412 may be provided. The transmission line, for example, may electrically connect the first processor 420-1 and the second processor 420-2, and communication may be performed between the first processor 420-1 and the second processor 420-2 through the transmission line. The transmission line may be implemented through a separate cable that passes through the third PCB 487 or the frame 197. The transmission line may be configured to support an interface protocol, such as an SPI, a universal asynchronous receiver transmitter (UART), or a universal serial bus (USB), but is not limited to the above examples.

Hereinafter, operations of the example vision system 412 and the example content system 410 will be described with reference to FIG. 5 . Hereinafter, it will be described that a method for processing contents and a vision of a distributed system implemented in the electronic device 401 is performed by the vision system 412 and the content system 410, but the disclosure is not limited thereto, and it will be understood that the content processing method may performed by the electronic device 401 or the first processor 420-1 and the vision processing method may be performed by the electronic device 401 or the second processor 420-2.

FIG. 5 is a schematic view illustrating the method for processing contents and a vision by the distributed system implemented in the example electronic device according to various embodiments. Referring to FIG. 5 , the vision system 412 according to an embodiment may acquire at least one image using at least one camera 480 (e.g., the first to fourth cameras 480-1 to 480-4 of FIG. 4 ). The vision system 412 may perform a user head-tracking and gaze-tracking operation, based on the acquired at least one image and a value detected using the at least one sensor 476 (e.g., the first to third sensors 476-1 to 476-3 of FIG. 4 ). The vision system 412 may acquire first data (or first information) on a motion of a gaze and second data (or second information) on a motion of the head of the user. Furthermore, the vision system 412 may acquire third information on an external object using the at least one camera 480 and the at least one sensor 476. For example, the third information may include information on a location of the external object (e.g., a TV) and tracking information on a speed and a direction of the external object with respect to the electronic device 401. The vision system 412 may transmit at least one of the first information, the second information, or the third information to an external electronic device 403. For example, the vision system 412 may transmit at least one of the first information, the second information, or the third information to the external electronic device 403 through a first communication network N1 established using the second communication circuit 492-2. Furthermore, the vision system 412, selectively, may transmit information on contents of an application (or an application that is being executed in a foreground) executed in the electronic device 401 to the external electronic device 403, together with the at least one of the information. In an embodiment, the first communication network N1 may include the first network 398 of FIG. 3 or the second network 399 of FIG. 3 . Additionally, the first communication network N1 may include a wired/wireless tethering connection between the electronic device 401 and the external electronic device 403.

In an embodiment, the external electronic device 403 may acquire screen information by rendering contents based on data (or information) received from the electronic device 401. For example, the external electronic device 403 may render contents related to the external object, based on the third information on the external object, which is received from the electronic device 401. The contents, for example, may include a visual object that represents information (e.g., a specification of a TV) related to an external object and/or a control menu (e.g., a menu for allowing the user to access a webpage, in which a TV may be purchased) related to the external object, but the disclosure is not limited to the above-described example. The visual object may be displayed to be adjacent to the external object or at least partially overlap the external object on the screen display part, but the disclosure is not limited thereto. The contents to be displayed may be rendered not by the external electronic device 403 but by a server 408 (e.g., a cloud server). In this case, the external electronic device 403 may transmit the data received from the electronic device 401 to the server 408, through a second communication network N2. The screen information acquired by the server 408 may be transmitted from the server 408 to the external electronic device 403 through the second communication network N2, and the external electronic device 403 may transmit the screen information to the electronic device 401. Furthermore, unlike the illustration, the external electronic device 403 may be omitted, and the acquired data on the motion of the user and the screen information based on thereto may be transmitted and received, between the electronic device 401 and the server 408, through the first communication network N1 or the second communication network N2.

The second communication network N2, for example, may include a short-range communication network (e.g., the first network 398 of FIG. 3 ), such as Wi-Fi, which is established through a wireless access point “A”. As another example, the second communication network N2 may include a 4th generation (4G), 5th generation (5G), or next-generation cellular network (e.g., the second network 399 of FIG. 3 ), which is established through a base station “B”.

In an embodiment, the content system 410 may receive screen information on the contents to be displayed, from the external electronic device 403 or the server 408. For example, the content system 410 may receive the screen information using the first communication circuit 492-1. In an embodiment, the content system 410 may display contents on the screen display part, based on the received screen information.

In an embodiment, the content system 410 may detect a motion of the user, while the contents are being displayed on the screen display part. For example, the content system 410 may detect a motion of the user and/or the external object using the first sensor 476-1 (or the first sensor 476-1 and a third sensor 476-3). For example, the content system 410 may detect a value of a posture of the electronic device 401 using the first sensor 476-1, and may determine whether the posture of the electronic device 401 is changed, based on the detected value. In this case, the content system 410 may determine that there is a motion of the user (or the electronic device 401 mounted on the user). In an embodiment, when a motion of the user and/or the external object is detected while the contents are displayed on the screen display part, the screen information received from the external electronic device 403 may be corrected based on the detected motion information (e.g., the fourth information). The content system 410 may output the corrected screen information on the screen display part. In an embodiment, the information on the motion of the user and/or the external object may be acquired by the vision system 412. In this case, the vision system 412 may transmit the motion information and a message that requests rendering such that the screen information is renewed based on the motion information, to the external electronic device 403 or the server 408. The external electronic device 403 or the server 408 may perform the rendering by renewing the contents, in response to the message received from the electronic device 401. The external electronic device 403 or the server 408 may acquire the renewed screen information. The vision system 412 may receive the renewed screen information from the external electronic device 403 or the server 408, and may display the renewed contents on the screen display part based thereon.

FIG. 6 illustrates a heat emission temperature of an example electronic device implementing the distributed system according to various embodiments. FIG. 7 illustrates a heat emission temperature of an electronic device, according to a comparative example.

Referring to FIG. 6 , because the content system 410 and the vision system 412 are distributed in the first arm 193-1 and the second arm 193-2, the heat emitted in the electronic device according to various embodiments may be uniformly distributed as a whole. This is because a current consumption of the content system 410 and a current consumption of the vision system 412 are similar. For example, the power consumption of the first processor 420-1 of the content system 410 may be about 300 mW, and the power consumption of the first communication circuit 492-1 may be about 250 mW. The power consumption of the second processor 420-2 of the vision system 412 on an opposite side may be about 550 mW. Furthermore, signal lines required by the content system 410 and the vision system 412 are distributed in the first arm 193-1 and the second arm 193-2, a design restriction due to a volume and a mounting space of the electronic device 401 may be reduced, and signal interferences that may be caused by signal lines of high densities may be reduced.

Referring to FIG. 7 , in an electronic device 701 according to the comparative example, both of the content system 410 and the vision system 412 may be disposed in the first arm 193-1. In this case, a temperature of the first arm 193-1 may be higher than that of the second arm 193-2. Accordingly, to reduce a deviation of emitted heat, the electronic device 701 according to the comparative example may require a separate heat dissipating structure in the first arm 193-1, and thus may degrade a comfort of wearing due to an increase and a deviation of the weight thereof. Furthermore, to solve the deviation of the weight due to the heat dissipating structure, the electronic device 701 according to the comparative example may require an additional structure for balancing the weight in the second arm 193-2.

Because the electronic device 401 according to various embodiments does not require a heat dissipating structure that is required in the above-described comparative example, an unnecessary increase of the weight may be prevented. Furthermore, the electronic device 401 according to an embodiment may maintain a balance of the weight even though there is no additional structure for balancing the weight, which is required in the above-described comparative example, and a comfort of wearing may be enhanced without any unnecessary increase of the weight.
